Reply to Pacemaker editor

Hi, I want to make dj mixes to put online or share with friends. I also want to edit tracks.
I was going to buy Live Intro for these tasks, however I currently use wavosaur for the editing and was planning to keep that. For the dj mix side of things, I saw this free software from the company that makes the pacemaker thing, the pacemaker editor.
I wanted to know should I do live intro for my purposes; use pacemaker for mixes and keep wavosaur for editing?
I also want to know if any one has used the pacemaker editor and give opinions of it? Thank you.
